A tube pump comprising a tube formed beforehand into a shape adapted for the inner circumferential face of the housing. With this configuration, the tube can be used without problems even when the inner circumferential face of the housing is small and when the curvature of the inner circumferential face is large, and squeezing can be carried out by applying a small pressure force to the tube. Hence, the size of the pump is prevented from being made larger, and breakage of the tube owing to repeated deformations does not occur because the amount of deformation of the tube is reduced. Furthermore, synthetic resins having high chemical resistance can be used as materials of the tube. Hence, unlike a rubber tube, the tube of the present invention is suited for a wide range of applications.
